Tharn Gate (or Tharn-Gate) is a fortified outpost and wall complex located at the only navigable pass through the eastern escarpment into Sanctuary Vale. Built directly into the stone terrain, it spans 6.5 miles in width and serves as both a controlled entry point and a strategic hub for logistics and oversight. The site is operated under the direction of the Council of Stone and remains continuously staffed and fortified.
Geography
The wall occupies a natural break in the escarpment, flanked by high cliffs to the north and fractured terrain to the south. Constructed from iron-bound basalt, the wall is layered with interlocking blocks and integrated observation towers. Internal access routes link major segments, while outer walkways provide high-elevation monitoring of pass activity.
History
Tharn-Gate was established following difficulties in regulating passage through the eastern escarpment. Early incidents of uncontrolled movement and terrain instability led the Council of Stone to commission a permanent structure. As usage increased, the outpost expanded into a full logistics and inspection center for eastbound and southbound travel.
Functions and Features
- Wall Span – The main structure extends 6.5 miles, incorporating reinforced gates and tiered walkways.
- Entry Hold – The inspection and clearance station for travelers, convoys, and supply carriers.
- Watch Bastions – Towered platforms along the wall used for observation and signaling.
- South Ledge Post – A remote platform positioned above unstable terrain to monitor southern movement.
Defenses and Watch
Tharn-Gate operates under permanent alert readiness. Gate segments are reinforced and independently sealed, with surveillance tools and communication links across the entire structure. In case of threat or terrain disruption, fallback procedures direct traffic toward rerouted corridors through Mar-Thal.
Threats and Dangers
Key risks include erosion, cliff collapse, and foundational stress from underlying fault lines. Storm seasons increase the probability of ground shift. Unauthorized crossings are rare but actively documented and investigated.
